FOOT-WARMER.

Specification of Letters Patent.

Patented Apr-11 21, 1908.

Application filed April 19, 1907. Serial No. `369,165.

To all whom 'it may concern:

Be it known that I, MARY E.'WALLER, a citizen of ythe United States, residing at Bethel7 in the county of Windsor, State of Vermont, have invented a certain new and useful Improvement in Foot-Warmers, of y which the following is a speciication, reference being hadtherein to the accompanying drawings.. V i p This invention relates to an article of manufacture for warming the feet. There are in use at .present many forms of hot water bottles and similar devices for this purpose, but these merely heat on one side of the foot, whereas this invention performs that function upon allsides.

It is a well known fact that heat applied to the top of the-foot and the ankle in particular has more eHect on the tem erature of the body and the circulation of t e blood than at any `other part of the body so that a Warmer which covers both the foot and ankle is materially advantageous over other types. It must be understood throughout this description and claims that the mention of foot includes ankle.

The feature of this invention is a shoe of rubber or other suitable material with an inner and outer layer, between which may be inserted a hot substance. Usually this heating substance is water, but air, sand or other sultable article might be used.` vAn opening is provided in this shoe, as will be more fully described hereinafter, similar to that found in the ordinary type, with a fastener or other suitable means for closing the same when the shoe is upon the foot. Loops are placed upon the top of the shoe to aid 1n pulling on the same.`

To protect the foot of the wearer from the heated surface of the rubber, a felt lining may p be placed within the shoe, but this mustbe removable to prevent its becoming damp. Such a lining is shown in the accompanying drawings.

A cock ofhoptional form is placed upon th J shoe to allow the heating substance to be put into the s ace between the inner and outer covers an it has been found advantageous to locate this near the toe of the shoe, though any other suitable location might be used.

The inner and outer layers of the shoe are preferably cemented only at the top of the ankle part and about the opening, already mentioned, to allow the heating substance free movement between them.

' The preferred embodiment of this invention as shown lows Figure 1 shows aside elevation of the invention complete. Fig.. 2 is a vertical section through the center of the ankle and foot in the 'drawings is as follWith all parts in front removed.

Referring to the drawings 1 is the outer layer of the shoe 2, the inner layer; 3, the felt lining; 4, the' place where the layers 1 andl 2 are cemented together; 6, the cock to close the a erture 6 by which the space be-l tween the ayers 1 and 2 is filled with the heating substance; 7, a rubber ring by means of which the`shoe may be held during the filli process', 8, an opening in the side of the s oe whic maybe opened to allow the -same tobe easily drawn on; 9, a clasp or button upon the flap 10 to close the opening 8;

and 1 1, 1 1 are the straps to be used in putting 'i on the shoe.

I claim as my invention and desire to secure by Letters Patent y 1. As a new article of manufacture, a shoe consisting of an inner and outer layer of material having a space between said layers,

the inner layer being suspended at its top I from the outer layer to allow relative motion between said layers.

2. As a new article of manufacture, a shoe consisting of an inner and outer layer having a space between 4said layers the inner layer being sus ended at its top from the outer layer to a low relative motlon between sald layers and means by which a'substancemay be placed between said layers. k

3. As a new article of manufacture, a shoe consisting of an inner and outer layer having Aa space between said layers the inner layer being sus ended at its top from .the outer layer to a low relative motlon between said layers, and one of said layers being provided Wlth a controlled opening leading to the space between said layers.

4. v As a new article of manufacture, a shoe consisting of an inner and outer layer of iiexlble material, said inner layer being suspended l' at its top from the outer layer to allow relative motion between said layers, and means for retaining the form of said inner layer.

5. As a new article of manufacture, a shoe consisting of an inner and outer layer of flexible material, said inner layer being suspended at its top from the outer layer to allow rela'- tive motion between said layers, and a supporting layerwithin said inner layer.

6. As a new article of manufacture, a shoe consisting of an innerand outer layer of ilexible material, said inner'layer being suspended at its top from the outer layer to allow relative motion between said layers, and means for allowing said shoe to be easily drawn upon the foot.

7. As a new article of manufacture, a shoe consisti of an inner and outer layer of flexible material, said inner layer being suspended at its top from the outer layer to allow relative motion between said layers, and a placket to allow said shoe to be easily drawn upon the foot.

8. As a new article of manufacture, a shoe MARY E. WALLER.
